[hardy] Latest HAL breaks guidance powermanager

[Mikael Gerdin]

Binary package hint: kde-guidance

kde-guidance-0.8.0svn20080103:

guidance-power-manager crashes at startup after HAL update 0.5.11~rc2-1ubuntu1
The latest HAL update has changed the keys for checking for suspend and hibernation support.
Old names: "power_management.can_suspend_to_ram" and "power_management.can_suspend_to_disk"
New names: "power_management.can_suspend" and "power_management.can_hibernate"

[Mikael Gerdin (mgerdin)]

This fix makes g-p-m use the new HAL-keys.

[Scott Kitterman (kitterman)]

Did we really upload something AFTER beta that changes function names without seeing what else it affects?

[Baronek (baronek1)]

I can confirm that bug.
Patch from Mikael Gerding solves issue for me.

[Launchpad Janitor (janitor)]

This bug was fixed in the package hal - 0.5.11~rc2-1ubuntu2

---------------
hal (0.5.11~rc2-1ubuntu2) hardy; urgency=low

  * debian/rules: build using --with-deprecated-keys, since we don't want to
    break packages that were assuming this worked right up through beta.
    LP: #204768.

[Scott Kitterman (kitterman)]

Please try again after you get hal 0.5.11~rc2-1ubuntu2 in your updates. That should fix it.

[Steve Langasek (vorlon)]

network-manager was also affected by the deprecated interfaces going missing. Since hal is fixed this isn't urgent for hardy, but should be cleaned up for intrepid.

It's better but still not it. That's what I get now :

[Scott Kitterman (kitterman)]

What version of power-manager do you have installed? I thought I fixed
that one.

[Olivier (olivier-lacroix)]

The latest available in hardy : 0.8.0svn20080103-0ubuntu7

[Scott Kitterman (kitterman)]

Looks like I missed a spot when fixing the Guidance part of Bug #183656. I'll take care of it.

[Olivier (olivier-lacroix)]

After a reboot the problem is gone. Thanks Scott

[Stuart Read (sread)]

Mikael Gerdin pointed me in the direction of this bug. I have not had any of the power management problems, but my network-manager crashes in a related manner (Bug #199066, Bug #145652). Relevant daemon.log is attached. Note that this problem remains with hal version 0.5.11~rc2-1ubuntu2.

[Stuart Read (sread)]

Network-manager debdiff in Bug #204868 fixes the problem. So this symptom is not a hal problem after all.

[Launchpad Janitor (janitor)]

This bug was fixed in the package kde-guidance - 0.8.0svn20080103-0ubuntu8

---------------
kde-guidance (0.8.0svn20080103-0ubuntu8) hardy; urgency=low

  [ Andreas Wenning ]
  * Added kubuntu_18_kde-powermanager_unique-check.patch:
    - Fixed guidance-power-managers check for being a unique app.
  * Added kubuntu_19_kde-powermanager_gpmhelper.patch
    (LP: #151444, #111143, #128666):
    - Added gpmhelper.py to listen for HAL button-events and issue
      dcop calls to guidance-power-manager.
    - guidance-power-manager will now start gpmhelper.py.
    - Patched setup.py to build/install gpmhelper.py
  * Changed debian/rules and debian/kde-guidance-powermanager.install
    to install gpmhelper.py
  * Added depends for kde-guidance-powermanager to python-gobject as
    this is the only mainloop to work with DBusGMainLoop.

  [ Scott Kitterman ]
  * Update kubuntu_12_powermanager_survive_no_brightness.patch so it correctly
    catches the error (LP: #183656)
  * Add kubuntu_20_displayconfig_no_resolutions.patch so displayconfig doesn't
    crash if current display size or refresh rate can't be fetched and similar
    changes for displayconfig-restore(LP: #147721, #110853)
  * Add kubuntu_21_powermanager_new_names.patch to use new hal keys
    (LP: #204768)
    - Patch thanks to Mikael Gerdin
